Did you continue and try the next step? The steps that you got errors on were to insert the ndiswrapper module which (according to the errors) appears to already be inserted so I *think* everything is fine so far.

I dont have luck to fix that. I reinstalled system and tried at once. I download ndiswrapper 1.55 - latest version. Intel driver was downloaded fromIntel web site. I go step by step in manual what you posted to me and I got error in dmesg.
